### 1、与switch语句联合使用 ###

[C++入门学习（二十三）选择结构-switch语句-CSDN博客][C_-switch_-CSDN]

#include <iostream>  
    #include <string>
    using namespace std;
      
    int main() {  
     
    int number;
     
    cout<<"请为《斗萝大路》打星(1~5※)：" <<endl; 
    cin>>number;
    switch (number) {
    	case 1:
    		cout<<"*"<<endl; 
    		break; 
    	case 2:
    		cout<<"**"<<endl; 
    		break;
    	case 3:
    		cout<<"***"<<endl; 
    		break;
    	case 4:
    		cout<<"****"<<endl;
    		break; 
    	case 5:
    		cout<<"*****"<<endl; 
    		break;
    	default:
    		cout<<"没有这个分数"<<endl;
    	 
    	
    	} 
     
    return 0; 
     
    }

如果没有break，会产生怎样的效果呢？我将上述代码中的break都删除一了，看一下结果吧：

### 2、与for循环结合起来 ###

[C++入门学习（二十六）for循环-CSDN博客][C_for_-CSDN]

#include <iostream>  
    using namespace std;
    int main() {  
        for (int i = 1; i <= 10; i++) {  
             if (i==6)
    		{
    			cout<<"666"<<endl;
    			break;
    		 }  
            cout <<i<<endl;  
          
        }  
        return 0;  
    }
